  • Assigning to struct in different class

    - by 4thSpace
    I have a struct in ClassA and want to assign it to the same struct in ClassB (the two structs are the same with different names). ClassA and ClassB are view controllers. Basically, I need to pass this struct to another class. However, structs don't seem to be exposed as members, which means I can't access them. Here is ClassA's struct declared in its header file: typedef struct { NSString *startDate; NSString *endDate; NSString *classId; } selectedItemsClassAStruct; selectedItemsClassAStruct selectedItemsClassA; and the same for ClassB (just with ClassA text replaced) It doesn't appear in code hints for ClassB. I see this error if I try to access it: request for member 'selectedItemsClassBStruct' in something not a structure or union How should it be done?

  • Adding More Than 2 Delegates in iPhone App

    - by golfromeo
    This is a simple question that can be answered fast by someone who's more familiar with Objective-C than I am- how can one add more than 2 delegates to a Class? To clarify, I'm used to putting delegates in classes like this: @interface ViewController : UIViewController <UIWebViewDelegate> { ... When I try to put two delegates: @interface ViewController : UIViewController <UIWebViewDelegate> <UITextFieldDelegate> { ... ...the app gives many errors, none of which help with the situation. Is there a separator that I need to put between the delegates, or is it possible at all to have more than two? Thanks for any help in advance.

  • iPhone development time...

    - by Tisch
    I have been asked to develop a relatively simple iPhone application. However, it would be my first application. I am a fairly competent programmer and can turn my skills to a new language fairly quickly... what my question is, is... How long has it taken some of you guys to make your first iPhone application and what was your experience like? Also, if you can say this sort of information, how much did you charge for it?! Thanks in advance. Kindest Regards Tom

  • SIGABRT Issues with UIApplication_TVOut and MPVideoView - is there another way??

    - by user365920
    Hi there, I am due to do a demo in a week of an app which i have been working on for a company - until now, i have been using code taken from this useful tutorial here The problem is that this no longer seems to be working - causing a SIGABRT inside of the following (see initWithVideoView): - (void) startTVOut; { // you need to have a main window already open when you call start if (!tvoutWindow) { deviceWindow = [self keyWindow]; MPVideoView *vidView = [[MPVideoView alloc] initWithFrame: CGRectZero]; **tvoutWindow = [[MPTVOutWindow alloc] initWithVideoView:vidView];** [tvoutWindow makeKeyAndVisible]; tvoutWindow.userInteractionEnabled = NO; mirrorView = [[UIImageView alloc] initWithFrame: [[UIScreen mainScreen] bounds]]; [self reformatTVOutOrientation]; mirrorView.center = vidView.center; [vidView addSubview: mirrorView]; [deviceWindow makeKeyAndVisible]; [NSThread detachNewThreadSelector:@selector(updateLoop) toTarget:self withObject:nil]; } } Can anyone help at all??? This was all working fine, but seems to have stopped working recently - none of my code has changed, so assuming Apple have removed that API (yes, i know it was a private API in the first place, so im not moaning!) Just need to know if there is an alternative way of displaying the contents of my iPhone screen in my app... Many thanks in advance!

  • touchesBegan and other touch events not getting detected in UINavigationController

    - by SaltyNuts
    In short, I want to detect a touch on the navigation controller titlebar, but having trouble actually catching any touches at all! Everything is done without IB, if that makes a difference. My app delegate's .m file contains: MyViewController *viewController = [[MyViewController alloc] init]; navigationController = [[UINavigationController alloc] initWithRootViewController:viewController]; [window addSubview:navigationController.view]; There are a few other subviews added to this window in a way that overlays navigationController leaving only the navigation bar visible. MyViewController is a subclass of UIViewController and its .m file contains: - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { for (UITouch *touch in touches) { NSLog(@"ended\n"); } } -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { for (UITouch *touch in touches) { NSLog(@"began\n"); } } I also tried putting these functions directly into app delegate's .m file, but the console remains blank. What am I doing wrong?

  • How can I grab the iTunes-defined name for my iPhone/iPod device?

    - by Christophe Porteneuve
    Hey there, I'm trying to get the name for an iPhone/iPod device that the user entered in their iTunes. This is not, I repeat, not, necessarily what [[UIDevice currentDevice] name] returns (or any of its other methods). For instance, my iPhone is bound in iTunes to "iPhone 3G de Christophe…", to differentiate it from my wife's and other similar devices. That's the name I'd love to be able to grab. Is it stored anywhere on the device, and if so can I access it somehow? Thanks!

  • What is the difference between these two different lines of Objective-C, and why does one work and n

    - by jrtc27
    If I try and release tempSeedsArray after seedsArray = tempSeedsArray , I get an EXEC_BAD_ACCESS, and Instruments shows that tempSeedsArray has been released twice. Here is my viewWillAppear method: - (void)viewWillAppear:(BOOL)animated { NSString *arrayFilePath = [[NSBundle mainBundle] pathForResource:@"SeedsArray" ofType:@"plist"]; NSLog(@"HIT!"); NSMutableArray *tempSeedsArray = [[NSMutableArray alloc] initWithContentsOfFile:arrayFilePath]; seedsArray = tempSeedsArray; NSLog(@"%u", [seedsArray retainCount]); [seedsArray sortUsingSelector:@selector(localizedCaseInsensitiveCompare:)]; [super viewWillAppear:animated]; } seedsArray is an NSMutableArray set as a nonatomic and a retain property, and is synthesised. However, if I change seedsArray = tempSeedsArray to self.seedsArray = tempSeedsArray (or [self seedsArray] = tempSeedsArray etc.), I can release tempSeedsArray. Could someone please explain simply to me why this is, as I am very confused! Thanks

  • Is it posible to Build & Run on TWO iPhones/iPods at once?

    - by Dimitris
    When I connect two iPhones at the same time to my computer and Build and Run a project the app only installs and plays on one of the devices. Now, with the iPhone 3.0, that supports bluetooth peer-to-peer connectivity, to test a multiplayer project you have to install and run it on two devices at the same time. It would be very helpful to be able to do that with one click instead of: install on one phone, disconnect, connect the other, wait a 10 seconds to recognize the phone and install again and run... Is anyone aware of a method to do such a thing? Thanks

  • How to get a list of installed android applications and pick one to run

    - by Jon
    I asked a similar question to this earlier this week but I'm still not understanding how to get a list of all installed applications and then pick one to run. I've tried: Intent intent = new Intent(ACTION_MAIN); intent.addCategory(CATEGORY_LAUNCHER); and this only shows application that are preinstalled or can run the ACTION_MAIN Intent type. I also know I can use PackageManager to get all the installed applications, but how do I use this to run a specific application? Thanks

  • Why MKMapView region is different than requested?

    - by Kamil
    Greetings! I'm saving map region into user defaults when my iPhone app is closing like this: MKCoordinateRegion region = mapView.region; [[NSUserDefaults standardUserDefaults] setDouble:region.center.latitude forKey:@"map.location.center.latitude"]; [[NSUserDefaults standardUserDefaults] setDouble:region.center.longitude forKey:@"map.location.center.longitude"]; [[NSUserDefaults standardUserDefaults] setDouble:region.span.latitudeDelta forKey:@"map.location.span.latitude"]; [[NSUserDefaults standardUserDefaults] setDouble:region.span.longitudeDelta forKey:@"map.location.span.longitude"]; When app launches again, i read those values back the same way, so that the user can see exactly the same map view as it was last time: MKCoordinateRegion region; region.center.latitude = [[NSUserDefaults standardUserDefaults] doubleForKey:@"map.location.center.latitude"]; region.center.longitude = [[NSUserDefaults standardUserDefaults] doubleForKey:@"map.location.center.longitude"]; region.span.latitudeDelta = [[NSUserDefaults standardUserDefaults] doubleForKey:@"map.location.span.latitude"]; region.span.longitudeDelta = [[NSUserDefaults standardUserDefaults] doubleForKey:@"map.location.span.longitude"]; NSLog([NSString stringWithFormat:@"Region read : %f %f %f %f", region.center.latitude, region.center.longitude, region.span.latitudeDelta, region.span.longitudeDelta]); [mapView setRegion:region]; NSLog([NSString stringWithFormat:@"Region on map: %f %f %f %f", mapView.region.center.latitude, mapView.region.center.longitude, mapView.region.span.latitudeDelta, mapView.region.span.longitudeDelta]); The region I read from user defaults is (not surprisingly) exactly the same as when it was saved. Notice that what is saved comes directly from the map, so it's not transformed in any way. I set it back on map with setRegion: method, but then it is different! Example results: Region read : 50.241110 8.891555 0.035683 0.042915 Region on map: 50.241057 8.891544 0.050499 0.054932 Does anybody know why this happens?

  • How do I get an imageview to rotate while translating in Android?

    - by Ravedave
    I am trying to make an imageview that rotates while sliding across the screen. I setup a rotate animation for 180 degrees, and it works by itself. I setup a translate animation and it works by itself. When I combine them I get an imageview that makes a big spiral. I would like the imageview to rotate around the center of the imageview while being translated. AnimationSet animSet = new AnimationSet(true); //Translate upwards and to the right. TranslateAnimation anim = new TranslateAnimation( Animation.ABSOLUTE, 0.0f, Animation.ABSOLUTE, +80.0f, Animation.ABSOLUTE, 0.0f, Animation.ABSOLUTE, -100.0f ); anim.setInterpolator(new DecelerateInterpolator()); anim.setDuration(400); animSet.addAnimation(anim); //Rotate around center of Imageview RotateAnimation ranim = new RotateAnimation(0f, 180f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f); //, 200, 200); // canvas.getWidth() / 2, canvas.getHeight() / 2); ranim.setDuration(400); ranim.setInterpolator(new DecelerateInterpolator()); animSet.addAnimation(ranim); imageBottom.startAnimation(animSet);

  • NSZombieEnabled hides EXC_BAD_ACCESS error entirely

    - by David Liu
    So I have a subclass of a UIView that starts causing EXC_BAD_ACCESS errors when I go through a specific set of conditions (run on iPad instead of iPhone or simulator, first login only). It throws the exception when the UIView subclass gets deallocated, during the last line, where I have [super dealloc]. I heard about using NSZombieEnabled, so I tossed that on to see if I could get any more information about it, but now it hides the error completely! Does anyone know a bit more about this type of situation? I thought NSZombie would start spewing stuff into my console like before, but I'm hoping that the nonexistance of errors would tell me some sort of information as well.

  • Sorting array containing strings in objective c

    - by jakob
    Hello experts! I have an array named 'names' with strings looking like this: ["name_23_something", "name_25_something", "name_2_something"]; Now I would like to sort this array in ascending order so it looks like this: ["name_25_something", "name_23_something", "name_2_something"]; I guess that should start of with extracting the numbers since I want that the sorting is done by them: for(NSString *name in arr) { NSArray *nameSegments = [name componentsSeparatedByString:@"_"]; NSLog("number: %@", (NSString*)[nameSegments objectAtIndex:1]); } I'm thinking of creating a dictionary with the keys but I'm not sure if that is the correct objective-c way, maybe there some some methods I could use instead? Could you please me with some tips or example code how this sorting should be done in a proper way. Thank you

  • custom cells uitableview - cannot display all the rows

    - by Matt Facer
    Hi guys, I'm creating a uitableview with custom cells which I created in Interface Builder. There are currently three cells (UITableViewCell). I have a UITableView which is on the view. The code I have is fairly standard, but I cannot work out how to actually SHOW the three custom cells. I am using the cellForRowAtIndexPath method. My aim is to get a grouped uitableview which shows like the following Item - Name Settings - alert - time So the above indented view should be my grouped uitableview. The problem is, I cannot get it to show using code. The uitableview will ALWAYS be this. I am trying to replicate the settings style screen... so I do not have any arrays to display the uitableview cells. How do I actually display my three cells? I have the following code - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 2; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { if (section == 0) return 1; else return 2; } - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { if(section == 0) return @"Item"; else return @"Settings"; } So all I need to know is how to actually display my custom cells inside the tableview! Thanks for any information. I've searched for AGES in google .. all the tutorials use arrays to display data!

  • Adding resources to solution explorer in experimental hive

    - by Brian Webb
    Hi, I'm currently working on a project using DSL tools in Visual Studio 2008. Is there a way to automatically add a resource into the solution explorer of the experimental hive at runtime? I'm creating new diagrams based on what is on screen, and saving them into the directory the project is stored in. I would like to know if there is a way to get them to automatically get added to the solution explorer? (I don't want to have to drag the files in manually each time)

  • Unit testing an iPhone static library with XCode 3

    - by teabot
    I am writing a number of static libraries for the iPhone and wish also to have suites of unit tests. XCode 3 provides templates for both static libraries and unit tests but I am wondering how they should fit together in a static library project? In my static library project I have created a target for unit testing but expect to also create an executable to kick off the unit tests than run against the classes in the static library. What is the procedure for doing this?

  • iphone - gesture not working on animated view

    - by Mike
    I have this animated view and a gesture assigned to it... [self.view setUserInteractionEnabled:YES]; UIImageView *sequence = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"frame0.png"]]; [sequence setUserInteractionEnabled:YES]; sequence.center = CGPointMake(centroX, centroY); NSMutableArray *array = [[NSMutableArray alloc] init] ; for (int i=0; i<30; i++) { UIImage *oneImage = [UIImage imageNamed:[NSString stringWithFormat:@"frame%d.png",i]]; [array addObject:oneImage]; } sequence.animationImages = array; sequence.animationDuration = 1.0; sequence.animationRepeatCount = 1; [self.view addSubview:sequence]; [sequence release]; sequence.startAnimating; sequence.image = [UIImage imageNamed:@"frame29.png"]; // doSomething never runs when I tap the image... why?

I have no other gesture associated anywhere. thanks for any help.

  • What could cause a button on a UIActionSheet to "miss" on touches?

    - by Alex Gosselin
    I have a UIActionSheet as follows: UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:[NSString stringWithFormat: @"Cancel New %@? Changes will be lost.", [creator propertyName]] delegate:self cancelButtonTitle:@"Stay Here" destructiveButtonTitle:@"Discard and Close" otherButtonTitles:@"Save and Close", nil]; [sheet showInView:self.view]; [sheet release]; It creates the action sheet, The buttons display, the Destructive button is on top, cancel button is on the bottom, other button (save and close) shows up in the middle, the top two buttons, (destructive and other) work fine, but the bottom button has a gap, so it is farther down than the other buttons. For some reason though, in order to press the button I need to touch where it would be if there was no gap. Touching the actual button doesn't work. Sorry if this isn't super clear, has anyone encountered something like this? I don't like to whip out the "I found a bug" card too fast, maybe I'm doing something wrong here.
